What is this?

This is a small library that allows you to programatically convert the PuTTY key file (.ppk) to the OpenSSH format.

Such a conversion relies on a few cryptographic operations that are not available out of the box from JDK, so this library depends on the trilead Java SSH2 library for those algorithms (but if you prefer to use this with other toolkits, you should be able to easily port this library.)
